Hey, I have a 2jz-ge-t swapped mk3 supra and the only gauge that works is my fuel level and speedo. What do I have to do to get the tach, temp, and oil pressure gauges to work? I’m currently swapping for a different cluster to see if that might help, but I’m open to suggestions on stuff to do while the cluster is out.

Your tach depends on the ignition system you're running, the ECU you're running, and the gauge cluster you have.

Temp and Oil pressure should be as simple as using the original 7M sensors on the 2JZ block somewhere and ensuring they're connected to your cluster wiring, assuming your wiring harness has that wiring intact.
